 SECTION 2. 
 REGISTRATION RIGHTS 
  

	 	2.1	Piggyback Registrations. The Company shall notify all Holders in writing at least fifteen (15) days prior to the filing of any registration statement under
the Securities Act for purposes of a public offering of securities of the Company (including, but not limited to, registration statements relating to secondary offerings of securities of the Company, but excluding a registration statement
(i) relating to any employee benefit plan or (ii) with respect to any corporate reorganization or transaction under Rule 145 of the Securities Act, including any registration statements related to the resale of securities issued in such a
transaction or (iii) related to stock issued upon conversion of debt securities) and will afford each such Holder an opportunity to include in such registration statement all or part of such Registrable Securities held by such Holder. Each
Holder desiring to include in any such registration statement all or any part of the Registrable Securities held by it shall, within seven (7) days after the above-described notice from the Company, so notify the Company in writing. Such notice
shall state the intended method of disposition of the Registrable Securities by such Holder. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, or if the Holder’s
Registrable Securities are excluded therefrom by the provisions of Section 2.1(a), such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration
statements as may be filed by the Company with respect to offerings of its securities, all upon the terms and conditions set forth herein. 

  

	 	(a)	 Underwriting. If the registration statement under which the Company gives notice under this Section 2.1 is for an underwritten offering,
the Company shall so advise the Holders. In such event, the right of any such Holder to be included in a registration pursuant to this Section 2.1 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion
of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form
with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this Agreement, if the underwriter determines in good faith that marketing factors require a limitation of the number of
shares to be underwritten, the number of shares that may be included in the underwriting shall be allocated, first, to the Company; second, to the Investors in accordance with the terms of the Investor Rights Agreement; third, to the Holders on a
pro rata basis based on the total number of Registrable Securities held by the Holders; and fourth, to any other stockholder of the Company (other than an Investor or a Holder) on a pro rata basis. No such reduction shall reduce the
amount of securities of the selling Holders included in the registration below twenty-five percent (25%) of the total amount of securities included in such



  

 3 









	 	 
registration; provided, however, that if such registration does not include shares of any stockholder of the Company other than Investors any or all of the Registrable Securities of
the Holders may be excluded in accordance with the immediately preceding sentence. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter,
delivered at least ten (10) business days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For any Holder
that is a partnership or corporation, the partners, retired partners and stockholders of such Holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing person shall be
deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in
such “Holder,” as defined in this sentence. 


  

	 	(b)	Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2.1 prior to
the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 2.2
hereof. 

  

	 	2.2	Expenses of Registration. Except as specifically provided herein, all Registration Expenses incurred in connection with any registration, qualification or
compliance pursuant to Section 2.1 shall be borne by the Company. All Selling Expenses incurred in connection with any registrations hereunder, shall be borne by the holders of the securities so registered pro rata on the basis of the number of
shares so registered. 

  

	 	2.3	Termination of Registration Rights. All registration rights granted under this Section 2 shall terminate and be of no further force and effect five
(5) years after the date of the Company’s Initial Offering. In addition, a Holder’s registration rights shall expire if (a) the Company has completed its Initial Offering and is subject to the provisions of the Exchange Act, and
(b) the requirements of paragraphs (c), (e), (f) and (h) of Rule 144 promulgated under the Securities Act do not apply to Registrable Securities held by and issuable to such Holder (and its affiliates) as a result of Rule 144(k)
promulgated under the Securities Act. 

  

	 	2.4	Delay of Registration; Furnishing Information. 

  

	 	(a)	No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise
with respect to the interpretation or implementation of this Section 2. 

  

 4 









	 	(b)	It shall be a condition precedent to the obligations of the Company to take any action pursuant to Section 2.1 above that the selling Holders shall furnish to the
Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be required to effect the registration of their Registrable Securities.


  

	 	2.5	Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Section 2 may be assigned by a Holder
to a transferee or assignee of Registrable Securities that (a) is a subsidiary, parent, general partner, limited partner, retired partner, member or retired member of a Holder, (b) is a Holder’s family member or trust for the benefit
of an individual Holder, or (c) acquires at least fifty thousand (50,000) shares of Registrable Securities (as adjusted for stock splits and combinations); or (d) is an Affiliate of such Holder provided, however, that
(i) the transferor shall, within ten (10) days after such transfer, furnish to the Company written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being
assigned, and (ii) such transferee shall agree to be subject to all restrictions set forth in this Agreement. 

  

	 	2.6	“Market Stand-Off” Agreement. Each Holder hereby agrees that such Holder shall not sell, transfer, make any short sale of, grant any option for the
purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Common Stock (or other securities) of the Company held by such Holder (other than those included in the registration) for a period specified
by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act;
provided that: 

  

	 	i.	such agreement shall apply only to the Company’s Initial Offering; and 

  

	 	ii.	all executive officers and directors of the Company and holders of at least one percent (1%) of the Company’s capital stock (on an as converted basis) and all
other persons with registration rights (whether or not pursuant to this Agreement) enter into similar agreements. 

  

	 	2.7	 Agreement to Furnish Information. Each Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company
or the underwriter that are consistent with the Holder’s obligations under Section 2.6 or that are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock
(or other securities) of the Company, each Holder shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the



  

 5 









	 	 
Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in Section 2.6 above and this Section 2.7 shall not apply to a
registration statement (i) relating to any employee benefit plan or (ii) with respect to any corporate reorganization or transaction under Rule 145 of the Securities Act, including any registration statements related to the resale of
securities issued in such a transaction or (iii) related to stock issued upon conversion of debt securities. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the
foregoing restriction until the end of the one hundred eighty (180) day period. Each Holder agrees that any transferee of any shares of Registrable Securities shall be bound by Sections 2.6 and 2.7. The underwriters of the Company’s stock
are intended third party beneficiaries of Sections 2.6 and 2.7 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 


  

	 	2.8	Stock Milestone Shares. In the event that the Company in 2006 issues additional shares of Common Stock to the Holders or any of their transferees as a 2005 stock
milestone payment pursuant to Section 2.5(c) of the Purchase Agreement (the “2005 Stock Milestone Shares”), the provisions of this Agreement as applicable to the Shares shall also be applicable to such 2005 Stock Milestone
Shares. 

  

	 	2.9	Indemnification. In the event any Registrable Securities are included in a registration statement under Section 2.1: 

  

	 	(a)	 To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, officers and directors of each Holder, any
underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint
or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any of the
following statements, omissions or violations (collectively a “Violation”) by the Company: (1) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state
securities law in connection with the offering covered by such registration statement; and the Company will pay as incurred to each such Holder, partner, officer, director, underwriter or controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending



  

 6 









	 	 
any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 2.9(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable in any such case for any such loss,
claim, damage, liability or action to the extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such
Holder, partner, officer, director, underwriter or controlling person of such Holder. 


  

	 	(b)	To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration
qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its directors, its officers and each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other
Holder selling securities under such registration statement or any of such other Holder’s partners, directors or officers or any person who controls such Holder, against any losses, claims, damages or liabilities (joint or several) to which the
Company or any such director, officer, controlling person, underwriter or other such Holder, or partner, director, officer or controlling person of such other Holder may become subject under the Securities Act, the Exchange Act or other federal or
state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished by such Holder under an instrument duly executed by such Holder and stated to be specifically for use in connection with such registration; and each such Holder will pay as incurred any legal or other
expenses reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, or partner, officer, director or controlling person of such other Holder in connection with investigating or defending any
such loss, claim, damage, liability or action if it is judicially determined that there was such a Violation; provided, however, that the indemnity agreement contained in this Section 2.9(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided further, that in no event shall any indemnity
under this Section 2.9 exceed the proceeds from the offering received by such Holder. 

  

	 	(c)	 Promptly after receipt by an indemnified party under this Section 2.9 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be



  

 7 









	 	 
made against any indemnifying party under this Section 2.9, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that
an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be
inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time
of the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.9, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.9. 


  

	 	(d)	If the indemnification provided for in this Section 2.9 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any
losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such
indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the
Violation(s) that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference
to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, that in no event shall any contribution by a Holder hereunder exceed the proceeds from the offering received by such Holder.


  

	 	(e)	 The obligations of the Company and Holders under this Section 2.9 shall survive completion of any offering of Registrable Securities in a
registration statement and the termination of this Agreement. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such



  

 8 









	 	 
indemnified party of a release from all liability in respect to such claim or litigation. 


  

	 	2.10	Rule 144 Reporting. With a view to making available to the Holders the benefits of certain rules and regulations of the United States Securities and Exchange
Commission (the “Commission”) that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its reasonable best efforts to: 

  

	 	(a)	Make and keep public information available, as those terms are understood and defined in Commission Rule 144 or any similar or analogous rule promulgated under the
Securities Act, at all times after the effective date of the first registration filed by the Company for an offering of its securities to the general public; 

  

	 	(b)	File with the Commission, in a timely manner, all reports and other documents required of the Company under the Exchange Act; and 

  

	 	(c)	So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request: a written statement by the Company as to its compliance with the
reporting requirements of Rule 144 of the Securities Act, and of the Exchange Act (at any time after it has become subject to such reporting requirements); a copy of the most recent annual or quarterly report of the Company; and such other reports
and documents as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing it to sell any such securities without registration.
